ASX ANNOUNCEMENT 31 August 2023
Massive & Disseminated Ni-Cu Sulphides Intersected – Mangaroon (Earn-in)
HIGHLIGHTS
-
RC drilling recently commenced at the Bookathanna North prospect along the 45km Money Intrusion, part of the Mangaroon Ni-Cu-PGE Project (First Quantum Minerals Earn-in). A total of 5 holes was planned for ~1,000m followed by down hole EM (“DHEM”).
-
The first hole (REYRC013, for 153m) was targeting a 37,000S conductor plate and has intersected ~14m of Ni-Cu sulphide mineralisation from 37m. The intersection includes 2m of massive sulphides and 12m of disseminated sulphides. The massive sulphides appear to be high tenor, comprised of 40-50% combined pentlandite and chalcopyrite in equal proportions.
-
REYRC013 was the first of 2 holes to be drilled at Bookathanna North where two highly conductive plates have been modelled over a ~100m strike. Based on these results, additional holes will be drilled and DHEM crews are mobilising to Bookathanna North. After Bookthanna North, the rig will move to High Range to test 3 further conductors.
-
Samples for REYRC013 are being rushed with assays expected in September 2023. Drilling is currently expected to take 1-2 weeks with assays and DHEM results expected in October 2023.
-
This program is fully funded by First Quantum Minerals.
Dreadnought Resources Limited (“Dreadnought”) is pleased to announce that RC drilling

has intersected significant visual Ni-Cu massive sulphides at the Bookathanna North prospect along the 45km long Money Intrusion part of the Mangaroon Ni-Cu-PGE Project, located in the Gascoyne Region of Western Australia.
Dreadnought’s Managing Director, Dean Tuck, commented: “Completion of our rare earths drilling programs has turned our attention to discovery focused drilling across our other projects and commodities. The intersection of shallow, high tenor massive sulphides in the first hole of this program is truly exciting and a great way to set the tone for the remainder of 2023. We are excited to return to the highly prospective Ni-Cu-PGE targets defined at Bookathanna North and High Range with our partners at First Quantum Minerals.”

SNAPSHOT – MANGAROON Ni-Cu-PGE
Major Miner, First Quantum Minerals, Earning-in
-
The potential of the Money Intrusion is underscored by an Earn-In with First Quantum Minerals Ltd (TSE:FM), a ~A$20B TSX listed company (ASX 7 Apr 2021, ASX 30 Aug 2022).
-
First Quantum Minerals can earn an initial 51% interest by funding $12M of expenditure by 1 March 2026. First Quantum Minerals may withdraw at any time during the earn-in phase with 0% interest.
-
Upon satisfying the earn-in requirements, a Joint Venture will be formed where First Quantum Minerals may elect to increase its interest to 70% by sole funding expenditure up until a Decision to Mine.
-
Once a Decision to Mine has been made, Dreadnought can elect to either:
-
Maintain its 30% by co-contributing.
-
Dilute to 20% and be loan carried by First Quantum Minerals, repaid through revenue.
-
Divest its 30% interest to First Quantum Minerals at fair market value.
-
Dreadnought retains gold rights across the earn-in tenements.
Fertile Ni-Cu-PGE System Confirmed
-
Fertile Ni-Cu-PGE sulphide systems are rare and the Money Intrusion has already been proven to contain high tenor magmatic Ni-Cu-PGE mineralisation.
-
The Money Intrusion is confirmed to be ~800Ma, a fertile time for Ni-Cu-PGE systems globally. Highly prospective keel geometries which are suitable for forming trap sites for magmatic sulphide accumulations have been identified.
-
First pass drilling in 2022 at the Bookathanna and High Range prospects intersected magmatic sulphide mineralisation including (ASX: 10 Nov 2022):
REYRC002: 13m @ 0.19% Ni, 0.17% Cu, 0.01% Co and 0.08g/t 3PGE from 70m
Including: 1m @ 0.85% Ni, 0.77% Cu, 0.46% Co and 0.17g/t 3PGE from 80m
REYRC009: 9m @ 0.11% Ni, 0.14% Cu, 0.01% Co and 0.10g/t 3PGE from 30m
Including: 1m @ 0.33% Ni, 0.44% Cu, 0.02% Co and 0.41g/t 3PGE from 31m
No Modern Exploration
-
Outcropping Ni sulphides were identified by Alan McDonald, the Pastoralist at Mangaroon in the early 1960s. However, no detailed geophysical, geochemical or mapping programs were ever undertaken.
-
The first-ever detailed airborne magnetics, surface geochemical, ground EM and mapping surveys have now confirmed the potential of the 45km long Money Intrusion.
Genuine Camp Scale Potential
-
Outcropping blebby sulphides have been confirmed over significant portions of the ~45km long Money Intrusion.
-
Multiple plumbing centres have been interpreted, each with the potential for trap sites within the magma pathways.
-
Mineralisation already confirmed by drilling at two prospects within the Money Intrusion: Bookathanna North and High Range.
Nickel and Copper are Critical to the Low Carbon Energy Transition
-
Nickel is essential to clean energy technologies including being a major cathode material in lithium-ion batteries. Furthermore, nickel sulphide deposits have a much lower carbon footprint when being converted to Class 1 nickel for battery grade applications.
-
Copper is essential for electricity-related technologies with renewable energy systems requiring up to 12x more copper compared to traditional energy systems.

Technical Discussion of Ni-Cu-PGE RC Drilling (REYRC013)
RC drill hole REYRC013 (153m) was drilled to test a 37,000S plate at the Bookathanna North prospect within the 45km long Money Intrusion and to provide DHEM geophysical conductors.
Drill holes were collared into the gabbroic core of the Money Intrusion before passing into the footwall olivine dolerite at 25m depth and finishing in gneissic country rock from 65m to 153m (EOH).
Drilling intersected disseminated Ni-Cu sulphides within the footwall olivine dolerite increasing in intensity to a 2m thick massive sulphide lens underlain by net-textured to brecciated sulfides. Logging details are shown in Table 1 below.
All sulphide mineralisation consists of pentlandite (Fe,Ni)9S8, chalcopyrite (CuFeS2) and pyrrhotite (Fe(1-x)S) with pentlandite and chalcopyrite making up ~40-50% of the sulphide mix with the remainder being pyrrhotite. In addition to the observed mineralisation, the presence of Ni and Cu was confirmed by handheld XRF.
An additional drillhole has been planned to test for down plunge mineralisation between the 37,000S plate and the 2,200S plate located ~100m along strike (Figure 5).

Technical Discussion of Ni-Cu-PGE Drilling Program (E08/3274, E09/2384: First Quantum Minerals Earn-in, up to 70%)
The confirmation of a fertile magmatic Ni-Cu-PGE system within the 45km long Money Intrusion highlights the potential for multiple deposits and/or deposit styles. The Money Intrusion has been dated to ~0.8 Ga, similar in age and tectonic setting to the Jinchuan Ni-Cu-PGE deposit in China (>500 Mt @ 1.2% Ni, 0.7% Cu, ~0.4 g/t PGE, Lightfoot 2007).
In 2022, 9 out of 12 RC holes intersected disseminated mineralisation along significant strike showing increasing width and intensity near subtle changes in the walls of the intrusion. These results highlighted the potential for massive sulphide mineralisation to concentrate and form at favourable "trap sites” along the intrusion. This is similar to Eagle and Eagle East (~5Mt @ 3.5% Ni, 2.9% Cu, 1.6g/t PGE, 0.1% Co, Lundin 2013) located in North America.
There remains significant potential for this system to host high tenor Ni-Cu-PGE massive sulphides. In 2022, a fixed loop EM survey was undertaken along strike from previous drill intercepts at Bookathanna and High Range where significant intercepts included (ASX: 10 Nov 2022):
REYRC002: 13m @ 0.19% Ni, 0.17% Cu, 0.01% Co and 0.08g/t 3PGE from 70m
Including: 1m @ 0.85% Ni, 0.77% Cu, 0.46% Co and 0.17g/t 3PGE from 80m
REYRC009: 9m @ 0.11% Ni, 0.14% Cu, 0.01% Co and 0.10g/t 3PGE from 30m
Including: 1m @ 0.33% Ni, 0.44% Cu, 0.02% Co and 0.41g/t 3PGE from 31m
Bookathanna North was targeted, as it was interpreted as a shallow keel position of the Money Intrusion, resulting in the identification of two conductors to the north being: one ~20x10m with a strong conductance of 37,000S, and another immediately adjacent, being ~40x10m with a high conductance of 2,200S (ASX: 24 Mar 2023).
High Range is located where the Money Intrusion crosses into a basin of Edmund Group Sediments. As expected, 3 lithological conductors perpendicular to the Money Intrusion were identified - each being ~50-100m x 50-70m with a high conductance of 750-900S (ASX: 24 Mar 2023). Each of these conductors is significantly stronger than the original Bookathanna conductor (~180S) which produced the net textured to brecciated sulphide intercepts in 2022.
Each of the 5 conductors was to be drilled by a single hole designed to test the centre of the modelled plates followed by DHEM surveys. However, based on the REYRC013 results, additional holes will be drilled and DHEM crews are mobilising to Bookathanna North. After Bookthanna North, the rig will move to High Range to test 3 further conductors.
This work is expected to take 1-2 weeks.

The Money Intrusion (E08/3178, E08/3274, E09/2384, E09/2433, E09/2473: (First Quantum Minerals Earn In))
The confirmation of a fertile magmatic Ni-Cu-PGE system within the 45km long Money Intrusion highlights the potential for multiple deposits and/or deposit styles. The Money Intrusion has been dated to ~0.8 Ga, similar in age and tectonic setting to the Jinchuan Ni-Cu-PGE deposit in China (>500 Mt @ 1.2% Ni, 0.7% Cu, ~0.4 g/t PGE,

Lightfoot 2007).
Jinchuan contains three main mineralised bodies over ~6.5kms of strike, each situated within a sub-chamber of the overall intrusion. Mineralisation is dominated by net-textured and disseminated sulphides with minor massive sulphide accumulations. Importantly, the disseminated sulphides form an envelope around the higher-grade, net-textured and massive sulphides. Furthermore, only one of the mineralised bodies is outcropping, with the other two deposits blind at surface (Figure 4).
The implications of the analogous Jinchuan deposits to the Money Intrusion are significant for both the current and future drilling. The first holes intersected disseminated mineralisation along significant strike showing increasing width and intensity towards the middle and at depth. There remains significant potential for this system to improve with depth and within the ~4.5km of strike already defined.
Furthermore, given the ~45kms of strike over the Money Intrusion shows evidence of pinching, swelling, multiple feeder channels and mapped disseminated sulphides, there could be significant mineralisation that does not outcrop.
Further drilling and geophysics along the intrusion will assist with better understanding the system and in identifying further mineralisation.
Figure 6: Plan view (top) and long section (middle) and cross section (bottom) of Jinchuan, highlighting that most of the mineralisation does not outcrop at surface (as appears to be the case with the Money Intrusion).

INVESTMENT HIGHLIGHTS
Kimberley Ni-Cu-Au Project (80/100%)
The project is located only 85kms from Derby in the West Kimberley region of WA and was locked up as a Defence Reserve since 1978.
The project has outcropping mineralisation and historic workings which have seen no modern exploration.
Results to date indicate that there may be a related, large scale, Proterozoic Cu-Au-Ag-Bi-Sb-Co system at Tarraji-Yampi, similar to Cloncurry/Mt Isa and Tennant Creek.
Mangaroon Ni-Cu-PGE JV & Au/REE 100% Project
Mangaroon covers ~5,200 kms and is located 250kms south-east of Exmouth in the Gascoyne Region of WA. At the Money Ni-Cu-PGE has been identified and is subject to an earn-in by First Quantum Minerals (up to 70%). Dreadnought also has areas of outcropping highgrade gold including the historic Star of Mangaroon and Diamonds gold mines. In addition, Mangaroon has emerged as a globally significant, rapidly growing, potential source of critical minerals. Highlights include:
- An Exploration Target of 50-100Mt at 0.9-1.3% TREO estimated for the top 150m of the ~43km long Yin REE Ironstone Complex (ASX 13 Feb 2023).
==> picture [247 x 329] intentionally omitted <==
-
An independent Resource for Yin Ironstones Complex of 20.06Mt @ 1.03% TREO over only ~4kms – including an Indicated Resource of 5.52Mt @ 1.23% TREO over just 250m strike (ASX 5 Jul 2023).
-
Regional source of rare earths at the C1-C5 carbonatites totaling ~9kms x ~1km (ASX 7 Aug 2023)
-
A large, independent initial Resource of 10.84Mt @ 1.00% TREO at C3, containing a range of critical minerals including rare earths, niobium, phosphate, titanium and scandium (ASX 28 Aug 2023).
Bresnahan HREE and Au Project (100%)
Bresnahan is located ~125km southwest of Newman in the Ashburton Basin. The project comprises ~3,700 sq kms covering over 200kms strike along the Bresnahan Basin / Wyloo Group unconformity. Bresnahan is prospective for unconformity related heavy rare earth (“ HREE ”) deposits similar to Browns Range HREE deposits and mesothermal lode gold similar to Paulsen’s Au-Ag-Sb deposits along strike.
Prior to consolidation by Dreadnought, the Bresnahan Basin had only been explored for unconformity uranium with limited exploration for mesothermal gold. Bresnahan is a first mover opportunity to explore for unconformity HREE.
Central Yilgarn Gold, Base Metals, Critical Minerals & Iron Ore Project (100%)
Central Yilgarn is located ~190km northwest of Kalgoorlie in the Yilgarn Craton. The project comprises ~1,600 sq kms covering ~150km of strike along the majority of the Illaara, Yerilgee and Evanston greenstone belts. Central Yilgarn is prospective for typical Archean mesothermal lode gold deposits, VMS base metals, komatiite hosted nickel sulphides and critical metals including Lithium-Caesium-Tantalum.
Prior to consolidation by Dreadnought, the Central Yilgarn was predominantly held by iron ore explorers and remains highly prospective for iron ore.

| Criteria | **JORC Code explanation ** | Commentary | ||||||||
| Sampling techniques | • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
RC Drilling Reverse Circulation (RC) drilling was undertaken to produce samples for assaying. Two sampling techniques were utilised for this program, 1m metre splits directly from the rig sampling system each metre and 2m composite sampling from spoil piles. Samples submitted to the laboratory were determined by the site geologist. 1m Splits Every metre drilled a 2-3kg sample (split) was sub-sampled into a calico bag via a Metzke cone splitter from each metre of drilling. 2m Composites All remaining spoil from the sampling system was collected in buckets from the sampling system and neatly deposited in rows adjacent to the rig. An aluminium scoop was used to then sub-sample each spoil pile to create a 2-3kg 2m composite sample in a calico. For gold and PGEs, all samples are submitted to the laboratory and pulverised to produce a 50g charge for Fire Assay (ALS Code PGM-ICP24). Base Metal and lithological samples are analysed for 48 multi- elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61) |
||||||||
| Drilling techniques | • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
RC Drilling Ausdrill undertook the program utilising a Drill Rigs Australia truck mounted Schramm T685WS drill rig with additional air from an auxiliary compressor and booster. Bit size was 5¾”. |
||||||||
| Drill sample recovery | • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
RC Drilling Drilling was undertaken using a ‘best practice’ approach to achieve maximum sample recovery and quality through the mineralised zones. Best practice sampling procedure included: suitable usage of dust suppression, suitable shroud, lifting off bottom between each metre, cleaning of sampling equipment, ensuring a dry sample and suitable supervision by the supervising geologist to ensure good sample quality. |
||||||||
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. |
RC Drilling RC chips were logged under the supervision of a qualified geologist with sufficient experience in this geological terrane and relevant styles of mineralisation using an industry standard logging system which could eventually be utilised within a Mineral Resource Estimation. Lithology, mineralisation, alteration, veining, weathering and structure were all recorded digitally. Chips were washed each metre and stored in chip trays for preservation and future reference. RC pulp material is also analysed on the rig by pXRF and magnetic susceptibility meter to assist with logging and the identification of mineralisation. Loggingis qualitative, quantitative orsemi-quantitativein |

| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
Preliminary pXRF analysis pXRF analysis of pulverised and partially homogenised reject RC sample piles is fit for purpose as a preliminary exploration technique. pXRF is a spot reading on raw (unprocessed) RC sample piles with variable grain sizes and states of homogenisation. High grade results were repeated at multiple locations to confirm repeatability. The competent person considers this acceptable within the context of reporting preliminary exploration results. RC Drilling From every metre drilled, a 2-3kg sample (split) was sub- sampled into a calico bag via a Metzke cone splitter or taken as a grab sample from the bulk reject in more clay-rich material. QAQC in the form of duplicates and CRM’s (OREAS Standards) were inserted through the ore zones at a rate of 1:50 samples. Additionally, within mineralised zones, a duplicate sample was taken and a blank inserted directly after. 2-3kg samples will be submitted to ALS laboratories (Perth), oven dried to 105°C and pulverised to 85% passing 75um to produce a 50g charge for Fire Assay with ICP-AES finish to determine Au and PGEs (PGM-ICP24) and 0.25g aliquot for four acid digest to determine 48 elements (ME-MS61) with overranges as required. Standard laboratory QAQC is undertaken and monitored. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Preliminary pXRF analysis Olympus Vanta M Series pXRF analyser is used to provide preliminary quantitative measurement of mineralisation. A 3- beam, 35 second reading time was used with a single reading on unprepared raw RC chip sample piles. High grade samples were repeated to confirm repeatability of grade. Calibration checks of the pXRF are undertaken daily, a silica blank and certified standard are routinely analysed to monitor pXRF performance. Laboratory Analysis Assay technique is Fire Assay which is a ‘Total Technique’ for Au and PGEs. Four acid digest is considered a ‘near total’ technique for the 48 elements received under ME-MS61. Standard laboratory QAQC is undertaken and monitored by the laboratory and by the company upon assay result receival. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
Preliminary pXRF analysis Analytical data was collected directly by the Olympus Vanta M Series pXRF analyser and downloaded by digital transfer to an excel spreadsheet with inbuilt QAQC. All data was checked by the responsible geologist and filed on the company server. Logging and Sampling Logging and sampling were recorded directly into a digital logging system, verified and eventually stored in an offsite database. Significant intersections are inspected by senior company personnel. No twinned holes have been completed at this time. No adjustments to any assay data have been undertaken. |
| Location of data points | • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
Collar position was recorded using a Emlid Reach RS2 RTK GPS system (+/- 0.2m x/y, +/-0.5m z). GDA94 Z50s is the grid format for all xyz data reported. Azimuth and dip of the drill hole was recorded after the completion of the hole using a Reflex Sprint IQ Gyro. A |

| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
See drill table for hole positions. The drill spacing is not suitable for resource estimation. |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
At this early stage of exploration, mineralisation thickness’s, orientation and dips are not known. Drilling was undertaken at a near perpendicular angle to the interpreted strike and dip of the modelled FLEM plates. No sample bias is known at this time. |
| Sample security | • The measures taken to ensure sample security. |
All geochemical samples were collected, bagged, and sealed by Dreadnought staff and delivered directly to ALS Laboratories Perth by Jarrahbar Contracting out of Carnarvon and Exmouth Haulage out of Exmouth. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
Historical exploration of a sufficiently high standard was carried out by a few parties which have been outlined and detailed in this ASX announcement including: Regional Resources 1986-1988s: WAMEX Reports A23715, 23713 Peter Cullen 1986: WAMEX Report A36494 Carpentaria Exploration Company 1980: WAMEX Report A9332 Newmont 1991: WAMEX Report A32886 Hallmark Gold 1996: WAMEX Report A49576 Rodney Drage 2011: WAMEX Report A94155 Sandfire Resources 2005-2012: WAMEX Report 94826 |
| Geology | • Deposit type, geological setting and style of mineralisation. |
The Mangaroon Project is located within Mangaroon Zone of the Gascoyne Province. The Mangaroon Project is prospective for orogenic gold, magmatic Ni-Cu-PGE mineralisation and carbonatite hosted REEs. |
| Drill hole information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
An overview of the drilling program is given within the text and tables within this document. |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Exploration Results are not being reported. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect _(e.g. ‘down hole length, true width not known’). _ |
Drilling is undertaken close to perpendicular to the dip and strike of the modelled EM plates. At this early stage, the relation between mineralisation and drill intercepts is unknown. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Refer to figures within this report. |
